Citicorp Center | NYC skyscraper saved by a student’s question

The Citicorp Center repair is a classic engineering case study of how mistakes must be avoided in engineering and construction of public works. A skyscraper in New York City needed a unique structural system. While reviewing the design a student asked a question that made the engineer realize that a mistake had been made. There is a daring race to make the repairs for the building collapses. The video gives the details and then discusses how the engineer handled the situation.
